The roadwarriors <b>carol</b> and <b>dave</b> set up a connection each to gateway <b>moon</b>.
|
||||
The authentication is based on trustworthy public keys stored as <b>IPSECKEY</b>
|
||||
resource records in the Domain Name System (DNS) and protected by <b>DNSSEC</b>.
|
||||
</p>
|
||||
Both <b>carol</b> and <b>dave</b> request a <b>virtual IP</b> via the IKEv2 configuration payload
|
||||
by using the <b>leftsourceip=%config</b> parameter. <b>leftfirewall=yes</b> automatically
|
||||
inserts iptables-based firewall rules that let pass the tunneled traffic. In order to test the
|
||||
tunnels, <b>carol</b> and <b>dave</b> then ping the client <b>alice</b> behind the gateway
|
||||
<b>moon</b>. The source IP addresses of the two pings will be the virtual IPs <b>carol1</b>
|
||||
and <b>dave1</b>, respectively.
